gstreamer: parse: Make sure children are bins before recursing in

Browse source 
A deferred set of the form parentbin::childelement::pad works in the
non-deferred property setting path, but the deferred path assumes that all
non-root non-leaf children specify bins. We already have a bin check on the
root, so let's add one for other non-leaves to avoid a critical.
